Hello! Lets solve this step by step! :) Okay so we are ganna use the Pythagorean theorem. Since we know that FG = 10 cm, BC = 8 cm, and AB = 9 cm, we can now plug those numbers into our equation. So we take  8 squared + 9 squared = c squared  So thats 81+64=c^2 145=c^2  and √145 =12.0415945788 Now we round it to the nearest tenth of a centimeter and that gives us 12.04  So thats our answer! :) Hope this helped if you have any other questions or would like further explanation just let me know!! :)
